Operating instructions
The operator must apply all relevant safety precautions. See section Safety precautions
during operation.
4.1 Initial start-up
The pump is supplied with oil in the gearbox.
Initial start-up instructions:
Remove the canopy panel(s) in order to get access to the internal components.
Check the process lines for the correct size to prevent high pressure drop and for cleanliness to protect the
pump.
Make sure the pump outlet is not obstructed.
Check that the electrical connections correspond to the applicable codes and that all wires are clamped tight to
their terminals. The installation must be earthed and protected against short circuits by fuses of the inert type in
all phases.
An isolating switch must be installed near the pump.
Check the oil level. The minimum level should reach the oil sight glass when the pump is stopped. If needed,
top up the oil.
Take care that no dirt drops into the oil system. Refit and tighten the filler plug.
Provide labels, warning the operator that:
– The pump may automatically restart after voltage failure (if activated, consult Atlas Copco).
– The pump is automatically controlled and may be restarted automatically.
– The pump may be remotely controlled.
Switch on the voltage and switch it off immediately. Check the rotation direction of drive motor while the motor
is coasting to a stop. The correct rotation direction of the drive motor is indicated by an arrow shown on the
motor fan cowl. If the rotation direction of the drive motor is incorrect, open the isolating switch and reverse two
incoming electric lines. Incorrect rotation direction of the drive motor may cause damage to the pump.
Start and run the pump for a few minutes. Check that the pump operates normally.
Open the inlet isolation valve.
Reinstall the canopy panel(s).
If you intend to apply the pump on humid applications, it is recommended that the unit is
allowed to achieve optimal running temperature before it effectively put in operation. This
can be done by running the unit against a closed suction line for 30 minutes.
